The 80 litre storage water heater Wesen ECO 80 is the built with the latest innovations. This electric boiler with a capacity of 80 litres has an energy label B! You will save significantly on your utility bill compared to a traditional cylinder-shape electric water heater. This water heater with two smaller tanks heats up to 60% quicker than the traditional storage water heater. Fitted with the latest PUR foam you will have superior heat retainment.

The Wesen ECO 80 with its modern and appealing design is very slim for an 80 litre electric water heater, with a depth of just 30 cm. The smart controller gauges your hot water consumption over a period of time and supplies hot water when you need it. This reduces the energy consumption drastically. The enamel steel tanks are highly durable and even suitable for hard water conditions.

The Wesen storage water heater is ERP ready, CE-marked and has a 2 year standard warrantee.

Please use the pressure relief valves free of charge to retain your warrantee. The valve with the red lever has a small orifice. You can connect the supplied discharge pipe to that orifice to drain of drops of expansion water. With this pressure relief valve you do not need an expansion vessel. This pressure relief valve has a non-return valve on the inside that prevents hot water from the water heater returning to the water mains that would create water hammer.

If you intend to use an expansion vessel please make sure you purchase a WRAS approved 7 bar pressure relief valve. This WRAS approved valve can only be used together with a WRAS approved check valve and a WRAS approved expansion vessel to retain your warrantee.

Using the wrong bar pressure relief valve can cause leakage inside the boiler as the working pressure inside the tank will exceed the maximum tank working pressure of 7 bar. It can also cause excessive calcification inside the tank. Calcification on the heating element slows heat transfer and will cause the heating element to overheat. Overheating weakens the steel and will eventually cause the steel to tear resulting in a short circuit.

We strongly recommend to install a pressure reducing valve if the water pressure is too high (5 bar or more) or if you suffer from fluctuating water pressure. High water pressure and/or fluctuating water pressure often occur in apartment building, flats, farms, older houses and houses and buildings in elevated areas. Install a pressure reducing valve where your mains water supply line enters your premises or right behind the pressure relief valve. Ensure the water pressure is set at 3 bar. Any damage caused by a too high water pressure or fluctuating water pressure will not be covered by the warrantee.
